B. Prepare For Heat Management
Introduction
An optional heat management system allows the heat from
the appliance to be redirected as desired.
An optional heat management system must be installed by
a quali
fi
ed service technician at the time of the appliance
installation. Follow the instructions shipped with the kit for
installation and operation.
NOTICE:
Additional clearances are required for heat
management systems installations. Provisions must be
made in advance to ensure
fi
t within the framing.
• Determine the heat management system(s) that will be
installed.
• Locate the two heat management ports on the top of the
appliance. Either one or two Heat-Zone
®
-Gas Kits may
be installed.
See Figure 6.2. Remove the knockouts
from the appliance with a tin snips.
• Center the duct collar or passive heat adapter around
the exposed hole and attach it to the appliance. See
Figure 6.5.
Note
: Do this BEFORE
fi
nal positioning of the appliance.
• Determine the location for the air register/fan housing
assembly.
Reference the Heat-Zone
®
-Gas Kit, Smart-Wall™ TV Kit,
Heat-Out-Gas Kit or Passive Heat instructions for the
remaining installation steps.
Heat Management System options are:
• HEAT-ZONE
®
-GAS: The heat is diverted into an
adjacent room.
• HEAT-OUT-GAS: The heat is diverted outside the
home/building.
• Smart-Wall™ TV Kit: The warm air from the appliance
is conveyed through an air duct to remote locations in
the same room or other rooms of the building.
• Passive Heat (PH-FRT-LINEAR, PH-SIDE-LINEAR):
The heat is vented into the room in which the appliance
is installed through a discharge opening(s).
WARNING! Risk of Fire!
DO NOT block passive heat
registers! Overheating of appliance and combustible
materials will occur.
The COSMO-B models may utilize two Heat Management
Systems, but not all are compatible.
The HEAT-OUT-GAS kit may be used with either HEAT-
ZONE
®
-GAS or one of the Passive Heat options.
Passive Heat may be used with HEAT-OUT-GAS or
one HEAT-ZONE
®
-GAS. The dedicated knockouts, as
shown in Figure 6.5, must be used only as indicated.
Passive Heat cannot be used with the Smart-Wall TV Kit
or optional fan.
Smart-Wall™ TV Kit
When a Smart-Wall™ TV Kit is installed, only one Heat-
Zone
®
-Gas kit or one Heat-Out-Gas kit may be installed.
The Smart-Wall™ TV Kit can not be used with a power
vent option or optional fan.
